SIP A call SIP B (no audio, OK) SIP B answer SIP A (audio OK) SIP B put onHold SIP A (SIP A audio OK, SIP B no audio-inactive) SIP B reinvite SIP A (SIP B audio activated, but SIP A audio is corrupted). I debug this, in sound_port.c, in method pj_status_t play_cb show (from and SIP A): if (frame.type != PJMEDIA_FRAME_TYPE_AUDIO) { PJ_LOG(4,(THIS_FILE, "frame.type(%d) != PJMEDIA_FRAME_TYPE_AUDIO(%d)", frame.type, PJMEDIA_FRAME_TYPE_AUDIO)); // added to me goto no_frame; } output: sound_port.c frame.type(0) != PJMEDIA_FRAME_TYPE_AUDIO(1) In random time, the audio callback ok. This situation, only ocurrs when the two clients are pjsua. Thanks for help. -------------- next part -------------- An HTML attachment was scrubbed...
